4E0953549 AUDI A8 D3 Steering Column Module + Clock Spring + Switches OEM Used & Tested

Descrizione

This listing is for OEM part number 4E0953549, a genuine used complete steering column switch assembly from the Audi A8 D3. The assembly has been removed from a donor vehicle, tested, and is ready to fit. It includes the indicator and wiper stalks, cruise control stalk, horn contact plate, and the clock spring (spiral cable unit) as a complete assembly.

This is the complete steering column switch assembly comprising the indicator and wiper stalks, cruise control or speed limiter switch stalk, horn contact plate, and the clock spring (spiral cable / squib unit). The clock spring is a flat wound ribbon conductor that maintains unbroken electrical continuity between the rotating steering wheel and the fixed wiring harness — carrying the driver airbag pyrotechnic circuit, horn circuit and all steering wheel-mounted control signals (audio, phone, cruise, paddle shifters). All steering column switch functions and the airbag squib circuit route through this assembly.

Driver airbag or SRS warning light on the dashboard — this is the most critical symptom as a broken clock spring can disable the driver airbag; horn completely non-functional; direction indicator or wiper stalks unresponsive; all steering wheel-mounted controls (audio, phone, cruise) failing to operate; SRS fault codes pointing to the spiral cable or clock spring unit stored in the airbag ECU.

Safety-critical assembly. Professional installation is essential — the airbag circuit is routed through the clock spring, and incorrect fitting can prevent the driver airbag from deploying. SRS fault codes must be cleared by a qualified technician with appropriate diagnostic equipment after fitting. Verify OEM number and vehicle specification before ordering. 14-day returns accepted on unmodified parts.
